MIC23656 SHORT OVERVIEW
The MIC23656 is a compact I
2
C programmable, high-efficiency, 6A peak current,
synchronous step-down regulator. The Constant-ON-Time (COT) control architecture
with HyperLight Load™ (HLL) provides very high efficiency at light loads, while still hav-
ing ultra-fast transient response. The user can program, via the I
2
C interface, various
parameters such as output voltage, ON-time, soft start slope, high-side current limit,
HLL or Forced PWM mode of operation. The 2.4V to 5.5V input voltage range, low shut-
down and quiescent currents make the MIC23656 ideal for single-cell, Li-Ion, bat-
tery-powered applications.
An open-drain Power Good (PG) output is provided to indicate when the output voltage
is within 9% of regulation and facilitates output voltage monitoring and sequencing.
When set in Shutdown mode (EN = GND), the current consumption of MIC23656 is
reduced to 1.5 µA (typical).
The MIC23656 is available in a thermally-efficient, 16-Lead
2.5 mm x 2.5 mm x 0.55 mm thin MLF package, with an operating junction
temperature range from -40°C to +125°C.
More detailed information regarding the capabilities of the MIC23656 are available in
the data sheet.
